1 Claim.

This invention relates to lighting nating arrangements, and particularlyto artools in the machine to become damaged because ofcond-itionsthatwould be observed under sufficient light.

Having the foregoing in mind, the

object of the present invention is. to providean- A still further objectis the provision of an par heavy presses, is generally almost comptember 1'5, 1949;. Serial Divided and this application Serial No.1%;481

illuminating arrangement for presses and the like so constructed thatoperating switches and the like can be incorporated therein, thusleading to a compact and efiicient arrangement.

In general the of this invention are obtubular light source in front ofthe working space of the machine and then movably positioning areflector behind the light source so the reflector can be adjusted todirect the light to the proper location. A bracket supports and housesthe illuminating means and reflector and can be used for supportingswitches and the like which are utilized in controlling the operating ofthe machine.

This application is a division of my application Serial No. 115,901,filed September 15, 1949, and assigned to the same assignee as theinstant application.

The foregoing objects and other objects and advantages of my inventionwill become more apparent upon reference to the following descriptiontaken in connection with the accompanying drawings, in which:

Figure 1 is: a front elevational view of a: by. i an illuminatingarrange draulic press. having ment according; to this invention;

Figure 2'. is an: enlarged view looking. in: dillrectly at the front ofthe press where thefillumihating. meansis mounted Figure 3. is ailluminating: means Figure: 4 is transverse section. 4 4- of. Figure 3;

Figure 5 is a taken on: line perspective view showing themeanssforadjustingi the positionof the reflector associated. with the:illuminating means; and: Figure 5 is. a sectional view indicated byline6-t on Figure 4' the: reflector can be: pivotally mounted relative tothe tube.

Referring to the drawings. somewhat more in. detail; the

The head includes a motor aving a ram L6 to which is attached: platen:I8, which also supports a blankholder .29; space .of the press isindicated at 22 between blankholder '20 and bed It and is adapted: for

configuration, dash outliines at; 2 4'. According, to the: presentinvention, a rail. or

bracket 25,, better illustrated in Figures. 2 and? 3;.

is mounted between working space, as by screws gated tubularilluminating element as which may be a filament type lamp or afluorescent or a neon tube, any of which are satisfactory for providingillumination. The tube 30, as will be seen the bracket.

In order to maintain the surface of the tube as clean as possible, thefront end of the bracket prise plastic or glass, although a plasticmaterial is usually to be preferred because of its resistance tobreakage.

Positioned behind tube 3t! is a reflector element 3% which may have itsend parts mounted about socket 3d, as indicated at it in Figure 6, so asto permit tilting of the reflector about the axis of the tube 39,thereby to direct the light from the tube toward the most advantageousposition in the working space of the press.

A lever 42 which is attached to reflector 38 perspective View showing.the? showing. one. manner in which:

The working extends out of a slot in the top of bracket 26 and isengageable by a detent arrangement 44, which provides for a plurality ofdifferent operative positions of the lever and reflector. This detentmechanism may comprise spaced spring fingers or spring strips, as may beseen in Fig ure 5, and is a convenient and inexpensive manner ofproviding this feature of adjustability.

In general, the arrangement of the tube and reflector as described willprovide for general illumination of the working Space with the reflectorfurther providing a somewhat increased illumination over a selected areaor zone within the working space, so that that part which must be mostclosely observed will be the best lighted.

The bracket 26 is made somewhat larger than is necessary for housing thetube and reflector and comprises a transverse channel arrangement 48 onthe operators side within which push-button stations, as at 48, may beprovided for controlling the operation of the press. This results in aconvenient manner of mounting the push-button stations or switches andalso positions them where they will be convenient for the operator tomanipulate.

Other switches or push-button stations which are less frequentlyemployed, such as those which determine that type of cycle the presswill operate, may be mounted on the uprights H2 at the ends of thebracket, as at 50, as will be seen in Figure 2. Those switches, however,which are to be operated on every cycle of the press are preferablylocated on the bracket 28, as described.

From the foregoing, it will be seen that my invention provides for arelatively simple, inexpensive, but nevertheless highly efficientarrangement for providing for illumination of the working space of amachine tool. The arrangement with other types of machine tools and thelike having a working space that requires illumination.

It will be understood that this invention is susceptible to modificationin order to adapt it to different usages and conditions, and,accordingly,

I it is desired to comprehend such modifications is such that itprovides not only general light- 0 ing, but localized lighting as well,where increased illumination is desirable.

The net result of utilizing my invention is to make the operation ofardous and more rapid with the assurance that a better product willresult because it can be better observed during operation.

The invention has been particularly described in connection with ahydraulic press, but it will be understood that it is adapted for use inconnection with other types of presses, as well as machine tools lessbaa-- within this invention as may fall within the scope of the appendedclaim.

I claim:

In a press an illuminating device oi the type described comprising: anelongated box-like hollow housing open along one side, a tubularlighting element in the housing, base members inside the ends oi thehousing to receive and sup port the ends of said lighting element, anadjustable reflector in said housing on the side thereof opposite theopening in said housing, said reflector having its ends journalled onsaid base members so as to be adjustable about the axis of said lightingelement, means to adjust said reflector comprising a transverse slot inthe upper surface of said illuminated housing, a rodlike handle membersecured to said reflector and extending through said slot, a detentarrangement including a plurality of notches along each side of saidslot and engageable with said handie member, thereby selectively lockingsaid handle member in a plurality of positions, and said housing beingprovided with a compartment extending lengthwise thereof inside the wallopposite the said opening, said compartment providing space to receivewiring and switches forming a part of the control system or" the press.
